C++ (Cpp) ref_ptr::getProjectionMatrix Examples

Example #1

File: CameraMath.cpp Project: kapecp/3dsoftviz

osg::Vec3d CameraMath::projectOnScreen( osg::ref_ptr<osg::Camera> camera, osg::Vec3d point )
{
	osg::Matrixd mv = camera->getViewMatrix();
	osg::Matrixd mp = camera->getProjectionMatrix();
	osg::Matrixd mw = camera->getViewport()->computeWindowMatrix();

	osg::Vec3d result = point * mv;
	result = result * mp;
	result = result * mw;

	return result;
}

Example #2

File: CameraMath.cpp Project: kapecp/3dsoftviz

bool CameraMath::isInFOV( osg::Vec3d point, osg::ref_ptr<osg::Camera> camera )
{
	double left, right, bottom, top, zNear, zFar;
	camera->getProjectionMatrixAsFrustum( left, right, bottom, top, zNear, zFar );

	osg::Matrixd& mv = camera->getViewMatrix();
	osg::Matrixd& mp = camera->getProjectionMatrix();
	osg::Vec3d pView = point * mv * mp;


	if ( pView.z() < 0.0 ) {
		return false;
	}

	return true;
}
